SAND FILTERS

Models: SF500, SF650, SF700 & SF800

FUNCTION

The filter uses special filter media to remove dirt particles from pool water. The filter media is loaded into the filter tank and functions as a permanent dirt removing media. When the multiport valve is in the FILTER position, the pool water which contains suspended dirt particles, is pumped through your piping system and is automatically directed by the patented filter multiport valve to the top of the filter tank. As the pool water is pumped through the filter, dirt particles are trapped by the media bed, and filtered out. The cleaned pool water is returned from the bottom of the filter tank, through the multiport valve and back to the pool through the piping system. This entire sequence is continuous and automatic. It provides for total recirculation of pool water through your filter and piping system. After a period of time, the accumulated dirt in the filter causes a resistance to flow, and the flow diminishes. This means it is time to clean your filter. With the multiport valve in the BACKWASH position, the water flow is automatically reversed through the filter so that it is directed to the bottom of the tank, up through the media, flushing the previously trapped dirt and debris out the waste line. Once the filter is back-washed of dirt, set the multiport valve to the RINSE position and run pump for about 15 to 30 seconds, and then set the multiport valve in the FILTER position, to resume normal filtering. NOTE: Turn pump OFF before changing the multiport valve position.

INSTALLATION

Only simple tools plus pipe sealant for plastic adapters are required to install and service the filter. 1. The filter should be placed on a level concrete slab, very firm ground, or equivalent. The filter should be placed in the right position so that the piping connections, multiport valve are convenient and accessible for operation and service. Position the tank with MPV in place to determine final position for piping. 2. Filter media is loaded through the top opening of the filter. a. (For 500/650) Loosen the flange clamp and remove filter multiport valve (if previously installed). a. (For 700/800) Loosen the flange Nuts and remove filter multiport valve (if previously installed). b. Cap internal pipe with plastic cap to prevent filter media from entering it. c. We recommend filling the tank approximately 1/2 way with water to provide a cushion effect when the filter media is poured in. This helps protect the under-drain laterals from excessive shock. d. Carefully pour in correct amount and grade of filter media. (Be sure centre pipe remains centred in opening.) Media surface should be levelled and should come to about the middle of the filter tank. Remove plastic cap from internal pipe. 3. Assemble filter multiport valve onto the filter tank. a. Insert multiport valve (with O’ring or casket in place) onto the tank neck, taking care that the centre pipe slips into the hole in the bottom of the valve. b. (For 500/650) Place clamp around valve flange and tank flange and tighten just enough so that the valve may be rotated on tank for final positioning. b. (For 700/800) Place nuts on all studs around valve flange and tighten just enough so that the valve casket seals (Do not over tighten). c. Carefully screw pressure gauge (with tread tape) into tapped hole in valve body. Do not over-tighten. d. Connect pump to multiport valve opening marked PUMP. After connections are made, recheck to ensure nuts or clamp band on multiport valve flange are tight. 4. Make the return to pool pipe connection to multiport valve opening marked RETURN and complete other necessary plumbing connections, suction lines to pump, waste, etc. 5. Make electrical connections to pump per pump instructions. 6. To prevent water leakage, make sure all pipe connections are tight.

INSTALL/START-UP OF FILTER

1. Make sure the correct amount of filter media is located in the tank and all connections have been connected and secured. 2. Depress multiport valve handle and rotate to BACKWASH position. (To prevent damage to multiport valve seal, always depress handle before turning.) 3. Prime and start pump according to pump instructions (be sure all suction and return lines are open), allowing the filter tank to fill with water. Once water is flowing out of the waste line, run the pump for at least 1 minute. The initial back-washing of the filter is recommended to remove any impurities or fine particles in the filter media 4. Turn pump off and set valve to RINSE position. Start pump and operate until water in sight glass is clear, about 30 seconds. Turn pump off and set valve to FILTER position and restart pump. The filter is now operating in the normal filter mode, filtering dirt particles from the pool water. 5. Adjust pool suction and return valves to achieve desired flow. Check system and filter for water leaks and tighten connections, bolts, nuts, as required. 6. Note the initial pressure gauge reading when the filter is clean. (It will vary from pool to pool depending upon the pump and general piping system.) As the filter removes dirt and impurities from the pool water, the accumulation of dirt in the filter will cause the pressure to rise and diminish the water flow. When the pressure gauge reading is 50kpa, higher than the initial "clean" pressure you noted, it is time to backwash the filter (see BACKWASH under filter and multiport valve functions). NOTE: During initial clean-up of the pool water it may be necessary to backwash frequently due to the unusually heavy initial dirt load in the water.
